Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a fixing/release bolt for a lever for opening a locking device, a knob for actuating the release lever, and a bolt individually controlled by an actuator. This invention relates to a releasable control device for a locking device of the type in which the locking/releasing lever is secured to rotate with the bolt rotor with play. In known devices of the type, the normal locking includes the locking of the operating knob, which can be forced by rough direct actuation in the event of a push-in. The purpose is to provide a connection between a releasable opening lever and a control knob by simple, reliable and economical means.

[First Means for Solving the Problem] To this end, the device according to the invention comprises an engagement slider controlled by a lock/release lever, which engages the operating knob in a fixed position. It is characterized in that it engages with the operation knob and the release lever at the release position when the resultant force 1 is removed.

The invention will be better understood from the following detailed description taken in conjunction with the accompanying drawings.

〔Example〕

The control device comprises an operating knob fixed to a cylindrical skirt 2 which pivots within the casing 3. Drive tongue S
The Poldro tag ending in is mounted coaxially with the skirt λ, and the operating knob/
The head 6 is flush with the outer surface of the head 6.

The driving tongue of the Poldro tag is angled into a slot 7 of a fixed/movable lever g to which one end of an actuating rod 7 is connected at its other end to an electric or pneumatic actuator (not shown). It is engaged with some play. A bistable spring 10, which is arranged in a known manner in the casing 3,
hole in lever g to ensure one stable position of /
/ cooperate with

The release lever 2 is freely attached to the skirt between the casing J and the lever. The opening connecting rod /3, which is connected to a locking device (not shown), is pivotally connected to the opening lever 7.2.

According to the invention, an engagement slider /l is provided to slide in the leftward direction of the opening lever=/2 groove/. The engagement slider puffer has an ear protruding toward which side of the lever, and it slides in the groove/7 of the lever g and the guide groove/g formed on the lever g and the ear part B. One end cooperates.

Spring/9 returns the lever to the closed position.

The casing 3 has a groove /S in the closed position of the opening lever 7.2.
The engagement groove 20 is provided to complement each other, and the engagement slider puffer is received at a fixed position. The surface 2/ of the engagement groove λθ is the release lever/ in the closed position, 1. form a stop body. Skirtco is a hole provided in the groove 15 at the closed position of the release lever/co and an extension of the engagement groove λ0,
It has 22. Which lever guide groove/g is the straight part u
It has a circular arc portion 23 lengthened by 4.

[For production]

The operating status of the control device is as follows.

In the unlocked closed position, the engagement slider
6 is received in the guide groove 1g of the lever at the connecting portion between the circular arc portion 23 and the straight portion 21IO of the guide groove/g. Tensioning the actuating rod 9 causes a certain rotation of the lever angle. The ear /6 is guided in the guide groove /which straight section 2g, causing an upward displacement of the engagement slider /da away from the hole 2.2. The release lever /2 is no longer fixed to the skirting board and the operating knob /2 rotates freely. Furthermore,
The engagement slide /lI is received at least partially in the engagement groove 20 of the casing 3 and is opposed to any attempt at pushing in by the action of the opening connecting rod /3 or the opening lever 7.2. The angular play of the slot 70 allows rotation A regardless of the presence or absence of the driving tongue S of the Poldro tag.

Starting from the previous unfixed position, skirt angle B
The rotation B+ of the operating knob / moves to the same unfixed position by the cooperation of the driving tongue j of the Poldro tag together with the slot of the lever g.

In the unfixed position, the engagement slider/rear hole, 2.2
The engagement groove λθ of the casing 3 completely protrudes from the engagement groove λθ. Therefore, the release lever /2 is the skirt 2.
The bolt rotor + toe (support) is fixed so that it can rotate. A rotation of the opening lever /2 through an angle C due to a corresponding rotation of the bolt rotor tuff exerts a thrust on the opening connecting rod /3 and causes unlocking of the locking device. In this rotation of the release lever /2 at angle C, the engagement slider /<1! Since the lug /6 moves into the arcuate portion 23 of the guide groove /g which is concentric with the entire locking device, the lever lug is not rotated.
